PECompact is a free and portable executable (PE) file compressor and decompressor for Windows. It can compress and decompress common PE file types like EXE, DLL, OCX, SYS, and more to significantly reduce their file size.
Reducing the file size is useful for more efficiently distributing software programs and libraries, saving disk space, and reducing download times. PECompact uses advanced compression algorithms to achieve high compression ratios with little impact on performance.
Some key features of PECompact include:
- Compression and decompression of EXE, DLL, OCX, SYS, and other PE file types
